A man was shot and two others injured and taken to hospital in life-threatening condition after Saturday's festival.

Investigators with the Special Investigations Unit work on Lake Shore Blvd. W. near the Molson Amphitheatre on Sunday where a man in his 30s was shot dead, a young woman was seriously injured and a man was grazed by a bullet along the Caribbean Carnival parade route the night before.

The Special Investigations Unit says police “interacted” with three men before a shooting that left one person dead and two others injured Saturday night along the Caribbean Carnival parade route.

Late Saturday leftover streamers and feathers littered the ground alongside police tape near the Molson Amphitheatre, where the shooting now being investigated by the SIU occurred.

A man in his 30s died, a 22-year-old woman suffered life-threatening gunshot injuries and another person was grazed with a bullet in the incident on Lake Shore Blvd. W.

The woman was undergoing surgery at St. Michael’s Hospital on Sunday, and the man’s name has yet to be released because police have not yet been able to notify his family.

“Police discharged their firearms; that’s why we’re there, but to what extent and how many and who, we can’t get to that yet,” said Frank Phillips, a spokesperson with SIU.

He said investigators were speaking with 14 witnesses between Saturday night and Sunday morning. No updates on the injured woman or the specifics of the deceased’s injuries were available.

The shooting occurred after the parade while revellers were still milling around.

Just after 7 p.m. sounds of gunshots rang out and several hundred people suddenly fled from the area, said an Exhibition Place grounds worker who declined to give his name.

“You could see a whole load of them running and then police running the opposite way,” said the man, who was cleaning some bleachers nearby when he heard the shots.

Both victims were rushed to a trauma centre, EMS officials said. The man was pronounced dead at the hospital.

EMS officials weren’t able to say exactly what their injuries were.

An 18-year-old bystander was also injured and taken to hospital after a stray bullet grazed his eyebrow.

Devan Boodram was elsewhere along the parade route on Lake Shore Blvd. W. when he heard his nephew had been grazed by a bullet. They had come from Scarborough with other friends and family to watch the parade.

He went to the scene of the shooting around 8:30 p.m. to see if he could find out any details from police.

A few dozen officers stood inside the area that had been fenced off to spectators during the parade. Some were interviewing witnesses.

“We just heard that there was a guy with a gun and our nephew was one of the bystanders who got grazed. We don’t know much yet,” said Boodram, who declined to name his nephew.

Ontario’s Special Investigations Unit has taken over the investigation. The unit probes cases of death, serious injury and allegations of sexual assault involving police officers.

The SIU issued a press release Sunday morning saying that police responded to a “disturbance involving three men” and that “officers interacted with the men and shots were fired,” but nothing more specific than that.

Six investigators and three forensic investigators have been assigned by the SIU to look into the incident. Phillips said he doesn’t yet know when news will be released about charges laid. He said the investigation may take longer than usual as investigators have to pick through the debris from the parade.

“There was not a patch of ground without a water bottle, pieces of costume, or garbage on it. We have to be careful to locate all of the evidence required,” he said.

Police said there was another shooting Saturday at 1 p.m. near Lake Shore Blvd. and Stadium Rd.

Earlier on Saturday, police identified the 23-year-old man who was shot to death in Etobicoke on Friday night. Anthony Smalling was shot at about 9:50 p.m. outside an apartment building on Capri Rd. near The East Mall.

Police also laid charges in a stabbing that occurred Friday near St. Patrick’s high school. A 17-year-old boy was charged with attempted murder, robbery, and two counts of assaulting a police officer with the intent to resist arrest.
